Abstract

We use an incoherent erase beam to control optical chaos and to increase the phase-conjugate reflectivity in a self-pumped phase-conjugate mirror. Focused and large-area incoherent illumination was used to modify or eliminate selected gratings in the crystal.

Enhancement of the phase-conjugate signal beam using selective erasure in an internally self-pumped conjugator. The inset gives the beam pattern in the self-pumped conjugator showing internal loops.

Fig. 3
Fig. 3

Plot of phase-conjugate reflectivity versus the area of the crystal illuminated by an incoherent erase beam. The data show the effects of illuminating increasing crystal areas starting from the exit face (open squares) and the entrance face (solid diamonds). The insets are diagrams showing illumination regions of the erase beam (shaded areas).
